Brisk ER14S Silver Racing Spark Plug – 1 Heat Range Colder (2015–2023 Hellcat)

Performance Spark Upgrade for Mild to Moderate Hellcat Builds

The Brisk ER14S Silver Racing Spark Plug is a high-performance upgrade for 2015–2023 Dodge Challenger and Charger Hellcat applications. Designed to be 1 heat range colder than stock, this plug is ideal for lightly modified to moderately upgraded engines running increased boost or aggressive tuning.

Silver Core Technology for Stronger Ignition

Featuring a 1.5mm fine wire silver center electrode, the ER14S delivers exceptional conductivity. Silver offers the best electrical and thermal transfer of any metal, resulting in a stronger spark, improved combustion efficiency, and better overall engine performance.

Optimized for Boosted Street & Performance Use

With a slightly colder heat range, this spark plug helps manage increased cylinder temperatures in supercharged applications, making it perfect for pulley upgrades, tuning, and bolt-on performance modifications while maintaining excellent drivability.

Projected Tip for Improved Combustion

The projected tip design enhances spark exposure within the combustion chamber, improving flame kernel development and throttle response. Combined with the cut-back ground electrode, this results in faster and more efficient combustion.

Reliable Performance Under Load

The ER14S offers excellent heat dissipation, reduced ignition voltage requirements, and strong resistance to fouling, ensuring consistent performance whether you're daily driving or pushing your Hellcat harder.
